The Orders database table uses Order_id as its primary key. You have written the following code to use in the Orders block of a form:
SELECT orders_seq.NEXTVAL
INTO :orders.order_id
FROM SYS.dual;
Which statement is true about this code?

You must be careful when coding a When-Button-Pressed trigger, because it does not accept restricted built-ins.

The Credit_Rating item in the Customers block of an Order Entry form must be restricted to three possible values: Good, Poor, or Null (the latter value indicates that the credit rating has not been determined). Order entry clerks must be able to update this item to any of the preceding three values.
You want to change the item to a check box labeled "Credit Risk" that should be selected if the customer has poor credit, the check box should not be selected if the customer's credit rating is good or undetermined.

You change the item type to Checkbox, set other properties as shown in the Exhibit, and then run your form and insert three records: two with good credit and the check box deselected, and one with poor credit and the check box selected. You commit the data and query the records, with the following result set:

The first two records show an undetermined credit rating, although your intention was to set the value to Good for these customers. What change must you make in the properties of the Credit_Ratinq item to enable values of Good, Poor, and Null to be entered?

A clerk is using the Human Resources form, which displays a department and its associated employees on the same canvas. Only two Items in the form are enabled.
Possible navigation units that can occur during navigation of this form are:
1. Outside the form
2. The Human Resources form
3. The Departments block
4. The Employees block
5. The current Departments record
6. The current Employees record
7. The Department_Id item
8. The Employee_Id item
With the cursor in : Departments.Department_Id, the clerk clicks the
:Employees.Employee_Id item.
What is the sequence of navigational unit movement that occurs?

You have been assigned to maintain a Forms application that was designed by a developer who has left the company.
The CV_Tools canvas contains several buttons. There is limited space on the canvas, but the first button is not quite wide enough to display its complete label. In the Layout Editor, you widen the button slightly and find that the width of all the buttons increases so that they now overlap each other.
What could have caused this problem?

In the Orders form, users often have a need to return to the first record. Because there are many employee records, it may take a long time for them to scroll up to the first record, so you create a button with the label First Record.
When users click the first Record button, you want to display your own custom message instead of the system message "FRM-40100: At first record." The system message should be displayed in other cases when users attempt to scroll above the first record.
You code the following When-Button-Pressed trigger:
:SYSTEM.mesage_level := '5'
UP;
WHILE FORM_SUCCESS LOOP
UP;
END LOOP;
MESSAGE ('This is the first Order');
The button works perfectly to return to the first record and display your custom message instead of the system message. However, users report that as they continue to use the form after clicking the button, no longer see other helpful messages. For example, the message "FRM 40102: Record must be entered or deleted first" no longer appears when they attempt to scroll past the last record.
How can you resolve this Issue so that all system messages continue to be displayed after the trigger code runs?

You are implementing a JavaBean in a form, the bean has no visible component on the form when invoked, the bean displays an input text where users enter a zip code, the bean has a single method that returns a short weather forecast for that zip code as a character value.
How can you retrieve that value so that you can display it to the user?

You want to display fields of a form module on multiple layouts that are visible simultaneously, what can enable you to achieve this?

Which statement is always true about a visual indicator that a text item has a list of values associated with it?
